10-46 regular D’Addario’s, usually in the bulk pack and when they are on sale. I used to use Slynkys, but had problems with string breakage during stretching. I heard others make the same complaint. JustStrings bulk packs are great as well, especially for the player who constantly restrings. The problem with theirs is they come by the dozen, by string gauge. I found that by the end of a dozen, they just didn’t feel ‘new’, maybe because the pack was open for too long?

Elixir all the way, because every other string rusts to hell in no time.
10-52 on the 24.75" scale guitars
11-49 on the Tele
11-52 on the Acoustics (custom light)
12-68 on the Baritone (27" tuned to BEADF#B)
10-46 + a single .068 on the 7-string (26.5" scale)
45-130 on the Basses (with a tapered B)

Only exception is the Epiphone Viola Bass, which carries Höfner Flatwounds

more or less stick with the same strings all the time,
EB 10's on electrics. Acoustics get either Elixir 13's , D' Add. EJ16, or M150's on the guitars that sound better with brass.
Elixir's are probably my favorite, they don't have that over bright new string sound and middle life is ages, well worth the extra cost
